AWS DMS replication instance upgraded to 3.5 and end point failing - Failed to get a table defination

Question

After upgrading an existing DMS replication instance to 3.5
an existing oracle source endpoint which was working pre upgrade is now encountering :

Test Endpoint failed: Application-Status: 1020912, Application-Message: Failed to get a table definition.

The login is a non admin login, it appears to be a missing permission post replication instance upgrade and / or a bug.
The endpoint works if I use an admin login (which I don't want to be using)
Please advise.

Many thanks when I added below to the non master user , the end point now works:

GRANT SELECT ON V_$SESSION TO myuser;
GRANT SELECT ON V_$MYSTAT TO myuser;

GRANT SELECT ON GV_$SESSION TO myuser;

Hello,

Currently, there is an issue identified with DMS Replication Instance version 3.5 leading to endpoint failure for Oracle as source with the following error:

“Test Endpoint failed: Application-Status: 1020912, Application-Message: Failed to get a table definition.”

The issue is specific to non-master users. You can grant the following privileges to your non-master user and test the endpoint connection.

```
GRANT SELECT ON GV$SESSION TO Username; 
GRANT SELECT ON V$MYSTAT TO Username;  
```
While ensuring required privileges are granted to the user -

[+] https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Source.Oracle.html#CHAP_Source.Oracle.Self-Managed

Alternatively, for time being, you may use the master user until the issue is fixed by the AWS internal team.

Thank you
